re: What's at the root of the problem between Nick and Lane?

If you believe Nicky, he only found out about LK being interested in other jobs this week. So, taking it for granted that LK is not leaving on his own with no job, his leaving has to on Nicky pushing him out the door. And after only a matter of days with this "issue" being out in the open between the two, there had to be other factors involved.
